Kumiho Braided USB C to Optical Audio Cable 3Ft Unidirectional USB C to Toslink Optical for TV/Soundbar, Sony PS5,Speakers & Home Theater Systems

An optical to usb c is probably the worst option out of all of the available options you have. If the guy you are replying to is correct then a straight coax to coax cable is what you want. Something like this. https://a.co/d/06oNOKOt An optical to optical cable is probably your second best option. Think about what you are saying with optical to usb c… at that point you are relying on the cable or dongle or whatever it is you are using to change the optical signal into usb c. I have no idea how that works but logically that just adds another step in the process and I don’t see how that could help the audio signal. If you are dead set on that idea for whatever reason then get something like this. https://a.co/d/01hliFpM Actually, after looking at it some more anll of the optical to usb options appear to be unidirectional but in the wrong way. Meaning the audio signal source would be on the usb c end and it sends it to the optical output. You are doing the opposite so I think what you are proposing isn’t even possible. Just stick with a straight coax or optical cable or get a new streamer if you are want to use that usbc port on the mimir.
